The Power of a Smile

Wikipedia defines a smile as “a facial expression formed by flexing the muscles near both ends of the mouth.” But, we all know that a smile can be so much more. Smiles are used to convey happiness, amusement and pleasure. They are a social communication tool that crosses international, racial, cultural and language boundaries. Lesser known are the positive and lasting effects that smiling can have on your life. Multiple studies have explored the physiologic and psychological benefits of smiling. “The Hidden Power of Smiling,” a TED* talk by Ron Gutman takes a closer look at some of these studies that affirm the power of a smile. A study at University of California Berkley linked the size of a person’s smile in their old yearbook photo to their current life’s well-being and success. Those with the widest smiles consistently scored better on standardized tests for general happiness, had higher rates of marriage happiness and length, and were found to be more inspiring to others. A Wayne State University study researched smiles on baseball cards in the early 1950’s. It found that the players who smiled in their photos lived, on average, seven years longer than the non-smiling players. A Penn State study showed that people appear more attractive, more likable and more competent when they smile. Smiling also make us feel better by producing endorphins and reducing levels of stress hormones such as cortisol and adrenaline. So now that you know the power of a smile, we hope that you’ll smile big and smile often!
